Application filed August 29, i903. Serial No. 171,214.

To alliwbom it may concern: v

Oris, a citizen ofthe United States, residing at Chicago,

in the county of Cook andState of Illinois, am the inventor of certain new and useful Improvements in Dump-Cars, of which the following isaspeciiicat-ion. v

f'My invention relates to that class of dump cars havings'winging dumping" bottom secr tions pivotally mounted at or near the longitudinal'center of the carreach movable into a horizontal closed' position to form a flat bottom car, and movable to an inclined position above the floor level, or.' downwardly 4 and. outwardly inclined position below the floor level ori-fpoint of pivotal connection with the car frame, whereby the'entire loadmaybe dumped upon either one side or the other of the car, as desired, o'i partly upon one side or partly upon the other.

A further object 4of my inventio'nis to so arrange the under frame and the doors in i relation thereto as to provide ample clearance for the lowering of t e doors to their' downvwardlyfinclined open position. .f The above mentioned and lother objects of my4 invention will appear more clearly from the following descriptionand claims, Atogether with the accompanying drawings, in Which.- f

Figure 1 is a sectional elevation of a car provided with my improvements showing i the dumping doors in position to forni a flat bottom car; Fig. 2 a similar view showing one of `the swinging bottom sections 1n horifzontal closed position and the other in inl clined closed position above the door level;`

` 3 a similar view showing oneof the` swinging bottom sections in inclined closed position and theother in inclined open position; Fig. 4 a detail sectional elevation, taken online 4 of Fig. 3 looking in the .direction ot the arrow, showing the flap for closing the, openings between the ends ofthe swinging sections'. over thedeck beams; and Fig. 5 a` f detailsectional elevation, taken online 5 of Fig. 3 looking in the direction of the arrow,

showing the Hap folded back over the swinging bottom section to permit it to swing into open inclined positionY to dump the load Fig. 6 is a plan viewV of a half of"a car constructed according to my invention.

tion I lia-veo y illustrated and described that which is new together only so much that is old and well-known in the art as is necessary to enable those skilled therein to.' make and practice the iii'ventionf-leavin out old and well known elements..

n the vention il ustrated in the vdrawings the load carrying longitudinal central sii orting means consists oi I-beams a, the two -beains adjacent the median linefbeiiig connected by acover platet ink a usual and well known manner. Upon the upper side of the I.

beams a, and resting thereon, are th'e transverse deck beams b, which' may also take the forni of I-beams. Upon the outer ends of the deck beams aremounted suitable side articular embodiment of my inframes c, which may be of any desired old and well-known type, and which, together with theordinary or any desired type of .end l frames, form asuitable load inclosing frame.

Each ofthe side frames is provided with suitablev inwardly extending longitudinally disposedboxes formed of inclined walls d i an suitable bottom'portions e, adapted to provide the necessary rigidity and strength to such inclinedwalls, al formed prefeia ly ,of metal and held in position upon the side'l frames by means of rivets f or in any ordinary and well-known manner, forming suitable g. 'I ese boxes extend overthe edges of the swinging dumpin sections when in their 'raised inclined position, so as to prevent the. contents o'iv the car, from passing over the The edges oi the raised dumping sections. operating 'rodshave chains attached thereto and alsoattached to theswinging sides of the dumping bottom sections hereinafter dei means of suitable eye-bolts i,V

scribed, b wlierebyt ev swinging bottom sections ma be raised and lowered as-desired and each supported in either its inclined closed position, horizontal closed position or open in-A clined position. The rotatable operating rods are adapted to be operatively' connected i with any suitable old and well-known means for operating them and holding them against rotation, such for instance as lever and ratchet mechanism which being well-known in the art need not be shown nor described. here.

Longitudinally disposed central I-beams are mounted intermediate the-deck beams already described upon the lower {iangps k thereof and upon the cover plate t so as"A to form suitable 'means forpivotally supporting ards for the rotatable operating rods nary and Well-known manner.

i. and suitable end frames-riot shown-are provided, forming with the side and bottom l frames the complete car' frame. These end iraines and holsters being old" and wellthem here.

connected with suitable operating ratchetdirection to raise the swinging dumping sec,-

their inclined closedposition as desired and permit sut-h sections on opposite sides to the swinging sections at the center of the ear, are made of suliicient width to place the ivotal point of such swinging sections at ,the desired elevation above the inain longitudi nal sills, and at the longitudinal median line ofthe ear.' The necessary incline is thus obtained to efficiently dischz'irge the load when the swinging sections are lowered to their open or discharging position. The construction 'described obviates -the neressity of a stationaryvi'loor plate over thc center sill, thus rendering it possible to discharge the eiitiie contents ol the car, the small quantity retained on the transverse deck beams beingI i negligible. The pivotal ioint of the swinging sections is made pre erably on substantially the same plane with the upper sides oi' the deck beams so as to aiiord a substantially i i known it is not deemed neeessar T to describe i ilatbottom car when the swinging sections are in horizont al closed position between the The operatimr rods q are adapted to he v b deck beams.

I claim:

opened inclinedv position to dump the load, such ratchet mechanism being, of course, provided with ordinary pawls for holding the rotatable rods so as to prevent rotation when It is desirable to provide means for closing the openings between the endsot adjacent swinging seetionsvhen elevated above the horizontal position. In the particular embodiment of my invention illustrated yin the drawings, I have shown for this purpose a suitable llap 1' pivotally mounted -upon the end of each swinging section to which it is attached by means of suitable hinges s, so that when the swinging sections are iii their elevated inclined position the openings between theni over the deuk beams may be closed as illustrated in Fig. 4. The ilapiiiiay be folded back over the swiiigiiigsecticnto which it is attached, as shown in 5, to permit such swinging section to move to its ower inclined position. When the swinging sections are in their horizontal position these fiaps are laid over the deck beams or folded i back as desired, and when the car is being able frame mounted upon such sill and beams, and a plurality ot' swinging dumping bottom sections pivotally mounted in the car frame, each movable into either inclined closed position, liorixoiital closed position or E inclined opened position as desired and exe tending from their pivotal points outward transversely of the car whei'iin each of su h positions, substantially as described. i l
